The study of vegetation bidirectional reflectance is useful for remote sensing data interpretation. Vegetation canopies information such as leaf area index, mean leaf inclination, mean plant height, and coverage, can be inverted from vegetation bidirectional reflectance. This paper discussed the dynamics of vegetation canopies reflectance with vegetation canopy structures by measuring rice canopy structure and bidirectional reflectance at 26, 35, 41, 49, 62, 67 and 86 days after transplanting. It is concluded that the sensitivity of vegetation canopies to directional reflectance variations varied with canopy structures, and hence, through bidirectional reflectance, more information about canopy structure can be know.
植被双向反射率的研究对于遥感数据解释很有用。诸如叶面积指数、平均叶倾角、平均株高和覆盖率等植被冠层信息，可以从植被双向反射率中反演得到。本文通过测量移栽后26、35、41、49、62、67和86天的水稻冠层结构和双向反射率，探讨了植被冠层反射率随植被冠层结构的动态变化。得出结论：植被冠层对方向反射率变化的敏感性随冠层结构而变化，因此，通过双向反射率，可以了解更多关于冠层结构的信息。
